C++ Programming Foundations

Learn C++ programming step by step, from Hello World, variables, input/output, branches, loops, arrays, strings, and functions to macros, headers, command-line arguments, pointers, object-oriented programming, exception handling, and file I/O, while building a first mental model for compilation, static types, and control flow.
